A ToQN Patented Apr. 1, 1930 UNITED STATES PATENT OFFICE AIBSHIPCONSTRUCTION Application filed January 17, 1929. Serial No. 388,111.

The invention relates to airship construction, as described in thepresent specification and illustrated in the accompanying drawings thatform part of the same.

L; The invention consists essentially .of the novel features ofconstruction pointed out broadly and specifically in the claims fornovelty following a description containin an explanation in detail of anacceptable iorm of the invention.

The objects of the invention are to utilize the wind and air currents tothe fullest advantage in stabilizing, poising, and propelling flyingmachines; to obtain good results from a particular arrangement of windrotors, whereby in the rotation of these rotors in the several planes,the movement of the air is both deflectedand turned to account in theoperation of the machine; to insure buoyancy without any great expanseof Wing and generally to provide in flymg machines a reliable swift anddurable type of ship.

In the drawings Figure 1 is a front elevational view of a flyingmachineof the airplane type.

Figure 2 is a plan view of the machine illustrated in Figure 1.

Figure 3 is an elevational view of the machine.

Figure, 4 is a cross sectional view on the lines 4-4 in-Figure 1.

Figure 5 is a front elevational view of a machine of the conventionalairplane type, showing an adaptation of this invention to such amachine.

Figure 6 is a side elevational view of a machine of another type,showing the application of this invention to a stream-line frame.

Figure 7 is a front elevational view ofthe invention, as illustrated inFigure 6.

Fi ure 8 is a front elevational view showing t e application of thisinvention to a box 15 is formed of the upper parallel stringers 16 andthe lower parallel stringers 17, spaced by the upri hts 18 and thehorizontal bars 19 and braced by the diagonal bars 20, thus formingframe sections.

The frame 15 is rigidly secured to and extends from the fuselage 21, inwhich a suitable motor is installed to drive the front propeller 22. Thefuselage supports a motor 23 driving the helicopter 24, the shaft ofwhich being journalled in the bearings 25 in the centre of the frame 15.

.The wind rotors 27 are arranged on either side of the helicopter 24 andextend in a transverse row in suitable number interrupted by saidhelicopter. The vertical wind rotors are mounted in the frame at theends and rotated in vertical planes. The vertical wind rotors 28 aremounted in a transverse row interrupted by the fuselage and rotatein-vertical planes transversely and thereby in this type of the machinecompleting the arrangement of wind rotors and buoyancy members, thefuselage being supported on the carriage 29 as customary in airplanes.

In Figure 5 the adaptation of this invention is to an airplane of thebi-plane type and on the wing 30, the frame 31 of extended coneconstruction forms at the apex of each cone a bearing for .each of thewind rotors 32, forming a transversely extending row of 30 wind rotorsabove the wing 30, rotating in horizontal planes. Between thewings 30and 33 the vertical wind rotors 34 rotating in a vertical planearesupported in their mountings by the diagonal bars 35, while the 5.

end wind rotors 36 are likewise mounted in the frame just beyond thewings and rotated in vertical planes in fore and aft directions. Thefuselage 37 is suitably attached to the wings 30 and 33 and carries themotor driven propeller 38, this fuselage being mounted on the carriage39, as customary m flying machines.

In Figures 6 and 7 the numeral 40 indicates the stream-line frametapering to a tail 41 5 and this frame carries the fore and aft row ofwind rotors 42 interrupted by the central motor driven helicopter 43,which is here shown-as driven by the motor 44 sup orted by the house 45in the interior of the ame. 10a

. dicates a box frame having the diagonal braces 53 supporting thebearings of several types of rotors. At the front of the frame, thepropeller 54 is driven by a motor contained in the house 55, while thehelicopter 56 rotating in a horizontal plane is driven by a motor in thesame house or thereabove'. The wind rotors 57 and 58 respectively aremounted in the frame at the top and bottom and rotate in horizontalplanes, and on the sides the wind rotors 59 and 60 respectively rotatein fore and aft directions in vertical planes. The rudder 61 extendsfrom this box frame 52 and completes the machine.

The frames'as illustrated show different types of this flying machineand, of course the frame may be round or it may be oval, octagon, or oterwise according to the plans of the constructing engineer, so long asthe salient features remain, namely the mounting of the wind rotors forrotation in vertical and horizontal planes as driving, buoyancy andstabilizing members.

Further these buoyancy and stabilizing members may be used onhydroplanes or even on deep sea vessels for stabilizing purposes,

but in the illustrations they are shown as applied to airships, thoughpractically similar applications may be made to other forms of s lps.

The operation of a machine of any of the forms described and containingthe same general type of buoyancy, stabilizing and propelling members isobvious from the description of the details of the drawings, for themachine. rises with the aid of the helicopter and the usual propulsionmember and the wind then lends a hand in the drivin floating andstabilizing of the machine, t rough the rotation of the several windrotors.

What I claim is 1. In airship construction, a fuselage, a frameextending from said fuselage and forming rotor bearings, a plurality ofwind driven rotors rotatable in a horizontal plane and suitablyjournalled in said frame, a plurality of wind driven rotors rotatable invertical planes and suitably journalled in said frame, a centralhelicopter motor driven and supported from the fuselage and a motor 2.In airship construction, a frame work, a plurality 0 wind rotorsrotating in a horizontal plane and a corresponding number in a arallelplane, fore and aft rotors rotating 1n parallel vertical planes,transverse rotors rotating in vertical planes, a lifting propeller and apropulsion member.
